Walky needs to learn some leadership techniques. Like, wait until someone is about to jump on their own, and then while they’re getting in position, quietly mutter a command to jump under your breath. And then they jump!

Also, order them to breathe. Some might resist, but that will only make it all the more impressive when they finally submit to your authority. Mike is probably the only one willing to hold his breath until he dies just to spite Walky.
